Pro Circuit R304 Silencer Yamaha YZ250

Developed as a full-race two stroke silencer, the Pro Circuit R-304 exhaust is constructed of a stainless steel intake tube and end-cap with a compact brushed aluminum canister. The compact design of the short canister decreases the amount of back pressure, which on a two stroke will increase throttle response and power in the low to mid RPM range.

The stainless steel end-cap of the Pro Circuit R-304 pipe is held in place with rivets, while the inlet cap is secured with hex head screws allowing for quick and easy disassembly when the time comes to replace the silencer packing.

Offering durability, easy maintenance, factory looks, and most importantly increased performance, the Pro Circuit R-304 will help deliver the full power potential of your two stroke machine.
